紋理數組在Java中

Question

的我有這樣的（正常工作）：

public static Texture bubble1 = new Texture(Gdx.files.internal("Bubble1.png")); 
public static Texture bubble2 = new Texture(Gdx.files.internal("Bubble2.png")); 
public static Texture bubble3 = new Texture(Gdx.files.internal("Bubble3.png")); 
public static Texture bubble4 = new Texture(Gdx.files.internal("Bubble4.png")); 

，我嘗試它（不要以任何方式工作）：

String fileName; 
Texture[] bubble; 
bubble = new Texture[4]; 

for (int i = 0; i < 4; i++){ 
    fileName = String.format("Bubble%1d", i+1); 
    bubble[i] = new Texture(Gdx.files.internal(fileName)); 
} 

有什麼不對？在維護代碼的簡單性和通用性的同時，我可以做些什麼來完成這項工作？ 非常感謝！

也許你忘了.png？

for (int i = 0; i < 4; i++) 
{ 
    fileName = String.format("Bubble%1d.png", i+1); 
    bubble[i] = new Texture(Gdx.files.internal(fileName)); 
}
